Description
Technical field
The present invention relates to bolt assembly technical field, specially a kind of bolt convenient for locking and can be locking.
Background technique
Bolt is conventional type fastener relatively conventional in daily life, has the zero of through-hole for being fastenedly connected two
Part, when use, need to cooperate with nut, and screw rod is inserted into hole in piece part, external force application means such as spanner etc. is reused and revolves nut
Tightly, though such bolt fastening is more common, in view of part has a demand property of disassembly, mistake when tightening nut or bolt
Big torque is unfavorable for the convenience of disassembly, and simple thread locking structure has its limitation, under biggish dynamic loading its
Self-locking reliability can reduce.
Summary of the invention
(1) technical problems to be solved
The present invention provides a kind of bolt convenient for locking and can be locking, disassembly and locking problem primarily directed to bolt；
Using technical solution provided by the present invention, the fast assembling-disassembling of bolt not only may be implemented, but also can after bolt screws
It effectively prevent its loosening.
(2) technical solution
To achieve the above object, the invention provides the following technical scheme: it is a kind of convenient for locking and can locking bolt, including
Camlock spanner, screw rod, nut, the camlock spanner are hinged on the non-threaded end of the screw rod, the nut installation
At the screw flight end；The screw rod includes the first screw rod, the second screw rod, inner screw, and the camlock spanner is hinged
In one end of first screw rod, the nut is mounted on second screw rod；The center of first screw rod is along axis side
It is equipped with perforative second connecting hole in the axial direction to the center for being equipped with perforative first connecting hole, second screw rod, it is described
Inner screw passes through second connecting hole and is mounted in first connecting hole；Along axis side in the second screw flight section
To rotation stop grooving is equipped with, the head of the inner screw is equipped with the rotation stop convex body cooperated with the rotation stop grooving；The inner screw
Head is back taper structure.
Through the above technical solutions, when being bolted part using this camlock spanner being gone to put first
The state of pine suitably tightens bolt on screw rod and then rotates clockwise drive the first screw rod rotation of camlock spanner, due to
It is threadedly coupled between inner screw and the first connecting hole, and the rotation stop convex body on inner screw head is mounted on the rotation stop grooving of the second screw rod
In, therefore the first screw rod is rotated relative to inner screw, inner screw precession into the first connecting hole, turns not moving cam when clockwise manually
When locking wrench, pull camlock spanner certain angle and connect fastening parts, at the same time inner screw head fall
Wimble structure, which enters in the second connecting hole, struts the thread segment of the second threaded rod, and then can be effectively prevented the loosening of nut.
When dismantling the bolt, pulling camlock spanner first loosens entire bolt, then rotates counterclockwise convex
Wheel locking wrench screws out inner screw out of first connecting hole, so that the back taper structure on inner screw head exits the second connection
Hole, convenient for users to disassembling nut from the second screw flight section.
In further technical solution, be socketed with screw jacket on the screw rod, on first screw rod its with it is described
Rotating cylinder is installed between screw jacket；The side of the screw jacket is equipped with rectangular hangnail outlet slot, and the hangnail
The length direction of outlet slot is consistent with the axis direction of the screw jacket, the opposite side in two positions of the hangnail outlet slot
Face is equipped with slot, and the spring leaf of strip is equipped in the slot, is equipped with hangnail group, the rotating cylinder on the spring leaf
Side be equipped with the protrusion that cooperates with the hangnail group.
In through the above technical solution, when being bolted part using this, rotation cam locking wrench drives the
The rotation of one screw rod, also with rotation, the hangnail group on protrusions press spring leaf on rotating cylinder side will for rotating cylinder on the first screw rod
It is released from hangnail outlet slot, is contacted with the connecting hole inner wall on part, is further improved bolted reliability；When tearing open
Camlock spanner is continued to rotate when unloading bolt, the protrusion on rotating cylinder side is separated with hangnail group, and hangnail group is in spring leaf
Under the action of reset, thus facilitate realize bolt disassembly.
In further technical solution, convex body A is equipped on the side of first screw rod in the axial direction, the rotating cylinder
Inner surface is equipped with the sliding slot cooperated with the convex body A；The setting can effectively ensure that rotation by the cooperation of convex body A and sliding slot
Drum rotation is driven while first screw rod.
In further technical solution, the hangnail group includes the hangnail body of strip, and the hangnail body is equipped with and institute
The hangnail of hangnail outlet slot cooperation is stated, the hangnail body is equipped with the spliced eye cooperated with the spring leaf；The setting is by falling
Hangnail body can be mounted on spring leaf by the cooperation of spliced eye and spring leaf on nematophore.
In further technical solution, ring-shaped rubber is being installed with camlock spanner connecting pin on the screw rod
Pad；The locking that ring-shaped rubber pad facilitates camlock spanner first is set, next plays anti-skidding effect, prevents camlock from pulling
Hand loosens.
In further technical solution, metal gasket is being installed with the nut connecting pin on the screw rod.
(3) beneficial effect
Compared with prior art, technical solution of the present invention, which has the advantage that, is divided into the first screw rod, for the screw rod
Two screw rods, inner screw, and the fast assembling-disassembling of bolt is realized in the cooperation for passing through the first screw rod, the second screw rod, inner screw, and in spiral shell
Bolt can effectively prevent its loosening after screwing；Telescopic hangnail device is set outside screw rod, passes through stretching for control hangnail
Bolted reliability can be further realized out.
